feat: enhance queue_status with execution-aware task sequencing (#29)

- Show plugin-level projectExecution setting in output
- Show project-level roleExecution for each project
- Sequential mode: single global task sequence across projects
- Parallel mode: per-project task tracks
- Proper handling of roleExecution within each project
- Priority ordering (To Improve > To Test > To Do)
- Visual distinction between active and upcoming tasks

Closes #21
